Description

Technical Field

[0001] The utility model relates to the technical field of eyeball models, in particular to an eyeball model structure. Background Art

[0002] Medical models are some medical simulation tools used or touched in medicine. They include a simulated human body as a whole and a simulated part of the human body or some simulated parts of the human body, as well as some medical instruments that must be involved in medical treatment. In order to facilitate the understanding of the structure of the eye, it is usually necessary to use a teaching eyeball model. According to the announcement number: CN219997725U, a teaching eyeball model is disclosed, including a fixed plate, and also including: a support adjustment mechanism is provided at the bottom of the fixed plate, a support seat is fixedly installed at the center position of the top outer wall of the fixed plate, a lower hemisphere is clamped on the top outer wall of the support seat, and a moving mechanism is provided on both sides of the top outer wall of the support seat near the rear of the lower hemisphere, and one end of the moving mechanism is provided with the same upper hemisphere, and the upper hemisphere fits on the lower hemisphere. The surface of the eyeball is formed by the upper hemisphere and the lower hemisphere. The cornea is fixedly installed on the front outer wall of the lower hemisphere in a position that fits the upper hemisphere. The utility model facilitates opening the eyeball structure from the middle to view the internal structure of the model, which is convenient for memorization and learning. The height of the model can be adjusted by the telescopic rod and the telescopic cylinder, and the movement of the upper hemisphere is driven by the sliding sleeve to open the inside of the eyeball. However, the above technology still has some defects. For example, traditional eyeball models often lack sufficient flexibility and stability, which makes it impossible to accurately reflect the actual situation when simulating eyeball movements. Due to the lack of effective fixing and adjustment mechanisms, these models are prone to displacement or shaking during use, which affects the accuracy of observation and experiments and needs to be improved. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems raised in the above background technology.

[0004] The utility model adopts the following technical solution: an eyeball model structure, comprising a lower eyeball, a lens installed on the surface of the lower eyeball, an upper eyeball installed on the surface of the lower eyeball, a column installed at the bottom end of the lower eyeball, a rotating plate installed at the bottom end of the column, a base provided at the bottom end of the rotating plate, a rotating plate installed at the top end of the base, a fixed plate installed on the surface of the rotating plate, a clamping rod provided inside the fixed plate, a stopper installed at the top end of the clamping rod, and a lifting block installed at the top end of the stopper.

[0005] Preferably, the rotating plate is rotatably connected to the base, and the top of the base is provided with fixing grooves, which are evenly distributed on the top of the base. Here, the movement of the eyeball is simulated more realistically.

[0006] Preferably, the clamping rod is slidably connected to the fixing plate via the clamping slot, and the clamping rod is slidably connected to the fixing slot and the base, thereby ensuring that the model can remain stable at different angles and heights.

[0008] Preferably, a protrusion A is installed on the back of the lower eyeball, a hinge is installed on the top of the protrusion A, and a protrusion B is installed on the back of the upper eyeball, and a card pad is installed on the surface of the upper eyeball. Here, it is more convenient to observe the internal structure of the eyeball.

[0009] Preferably, the protrusion B is rotatably connected to the protrusion A via a hinge, and the hinge is symmetrically distributed on the top of the protrusion A. Here, the rotation of the eyeball is simulated more realistically.

[0010] Preferably, the clamping pad is arranged at the center of the surface of the upper eyeball, and the clamping pad is slidably connected to the lens. Here, the position and angle of the lens can be flexibly adjusted during use of the model.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] See also Figure 1-4The present invention provides a technical solution: an eyeball model structure, comprising a lower eyeball 1, a lens 2 mounted on the surface of the lower eyeball 1, an upper eyeball 3 mounted on the surface of the lower eyeball 1, a column 4 mounted at the bottom end of the lower eyeball 1, a rotating plate 5 mounted at the bottom end of the column 4, a base 6 provided at the bottom end of the rotating plate 5, a rotating plate 7 mounted at the top end of the base 6, a fixed plate 9 mounted on the surface of the rotating plate 5, a clamping rod 11 provided inside the fixed plate 9, a stopper 12 mounted at the top end of the clamping rod 11, and a lifting block 13 mounted at the top end of the stopper 12. By arranging the rotating plate 5, base 6, rotating plate 7, fixing slot 8, fixing plate 9, clamping slot 10, clamping rod 11, stopper 12, and lifting block 13, a more realistic reproduction of eyeball movement is achieved. In addition, the design of the fixing plate 9, clamping rod 11, and stopper 12 enables the model to be stably fixed in a specific position, facilitating detailed observation and analysis. This structure not only improves the stability and operability of the model, but also enhances its application value in education and research. The rotating plate 5 is rotatably connected to the base 6 through the rotating plate 7. A fixing groove 8 is provided at the top of the base 6. The fixing groove 8 is evenly distributed on the top of the base 6, which simulates the movement of the eyeball more realistically. The fixing grooves 8 opened at the top of the base 6 are evenly distributed, providing a stable and adjustable fixing point, ensuring that the model can be firmly fixed in a specific position, facilitating detailed observation and analysis. The card rod 11 is slidably connected to the fixed plate 9 through the card slot 10. The card rod 11 is slidably connected to the fixing groove 8 and the base 6, ensuring that the model can remain stable at different angles and heights. The sliding connection between the card rod 11 and the base 6 further enhances the stability of the model, preventing shaking or displacement during use. The fixing plate 9 is rotatably connected to the base 6, and the stopper 12 is slidably connected to the fixing plate 9, thereby more flexibly simulating the movement of the eyeball. The sliding connection design between the stopper 12 and the fixing plate 9 provides additional stability and adjustment function, ensuring that the model can maintain a specific position and angle during use.

[0025] Example 2

[0026] See also Figure 1-35. A protrusion A14 is installed on the back of the lower eyeball 1, and a hinge 15 is installed on the top of the protrusion A14. A protrusion B16 is installed on the back of the upper eyeball 3, and a card pad 17 is installed on the surface of the upper eyeball 3, which makes it easier to observe the internal structure of the eyeball. When in use, when it is necessary to observe its internal structure, pinch the upper eyeball 3 and pull it upward, so that the upper eyeball 3 can be rotated upward at the top of the upper eyeball 3 through the protrusion A14, the protrusion B16 and the hinge 15. When the upper eyeball 3 is completely turned away, it can be used, thereby improving the flexibility and durability of the model and enhancing its application effect in education and research. The protrusion B16 is hinged The hinges 15 are rotatably connected to the protrusion A14, and the hinges 15 are symmetrically distributed on the top of the protrusion A14, thereby more realistically simulating the rotation of the eyeball. The hinges 15 are symmetrically distributed on the top of the protrusion A14, ensuring the stability and balance of the rotation. The pad 17 is set at the center of the surface of the upper eyeball 3, and the pad 17 is slidably connected to the lens 2, so that the model can flexibly adjust the position and angle of the lens 2 during use, thereby more accurately simulating the focusing mechanism of the eyeball. This design not only improves the operational flexibility and practicality of the model, but also enhances its application effect in education and research.

[0027] Working principle: When in use, place the lower eyeball 1 in the required position, and make the base 6 support the lower eyeball 1 firmly through the column 4. At this time, observation and teaching can be carried out through the lower eyeball 1, the lens 2 and the upper eyeball 3. When it is necessary to adjust the angle during use, first pinch the lifting block 13 and pull it upward, so that the lifting block 13 drives the card rod 11 to slide upward through the stopper 12. At this time, the card rod 11 slides upward inside the fixing plate 9 through the card slot 10 and slides out of the base 6 through the fixing slot 8. When the card rod 11 completely slides out of the base 6 through the fixing slot 8, it is ready. Pinch the fixed plate 9 and rotate it so that the rotating plate 5 rotates on the top of the base 6 through the rotating plate 7, and the rotating plate 5 drives the lower eyeball 1, the lens 2 and the upper eyeball 3 to rotate together through the column 4 to achieve the adjustment effect. When it is necessary to demonstrate the internal structure during the teaching process, pinch the upper eyeball 3 and pull it upward so that the upper eyeball 3 rotates upward on the top of the bump A14 through the bump B16 and the hinge 15. At this time, the upper eyeball 3 drives the clamping pad 17 to slide upward together. When the clamping pad 17 slides out of the back of the lens 2 and the upper eyeball 3 is completely rotated away from the top of the lower eyeball 1, it is ready.
